Application filed August 26, 1914. Serial No. 858,651.

To all whom t may concern Be it known that 1, JOHN F. JENSEN, a citizen of the United States, and resident of Union Hill, in the county of Hudson and State of New Jersey, have invented a new and useful Improvement in Non-Refillable Bottles, of which the following is a specification..

rfhis invention relates to nonrellable bottles with the object of producing such a structure which is quite simple and yet effective; which may be easily constructed, and which will act against either direct refilling or such operation by the assistance of a vacuum.

Another object is to provide certain improvements in the form, construction and arrangement of the several parts which will effectively carry out the above named and other advantages.

A. practical embodiment of my invention is represented in the accompanying drawings, in which- Figure 1 represents a vertical section through a bottle neck with the invention applied, Fig. 2 represents a similar view with the bottle in position for delivering the contents, Fig. 3 represents a vertical section through the cork seat, Fig. 4 represents a similar view of the cage, Fig. 5 represents a similar view of the valve, Fig. 6 represents a similar view of the valve seat, and Fig. 7 represents a similar view of the washer.

The bottle neck is denoted by 1 and is provided, intermediate its ends, with an annular shoulder 2, which shoulder is adapted to support a valve seat 3, with the interposition of a washer 4, of cork or other suitable material, for effecting a liquid tight engagement.

The valve seat 3 is preferably composed of glass or porcelain, and has a contracted opening from which the surfaces flare away, as clearly shown in Figs. 1, 2 and 6, thus forming both an interior and exterior seat for the valve heads, to be hereinafter described, This valve seat has its periphery fashioned to conform tightly to the interior of the bottle neck, and its upper or outer portion is reduced in order to snugly receive the open end of a cylindrical cage 5, which has its outer surface fitted to the inside of the neck. At its outer end the cage 5 is contracted so as to have an opening 6, of relatively small diameter, which opening is surmounted by a hollow cap 7, having openings 8 in its sides. This cage is also preferably made of glass or porcelain. Y

Fitted over the mouth of the bottle and projecting therewithin to contact with the cage .3, is a cork seat 9 (of glass or porcelain), which has a central opening therethrough for the reception of an ordinary cork 10. rThe portion of the cork seat 9 which extends within the bottle neck has its outer surface contracted toward the center of the said seat, as indicated at 11; and diagonal passages 12 are provided in the outer part thereof for opening communication from the exterior to the space between the surface 11 and the neck of the bottle. rEhe purpose of the arrangement is to provide convenient means for sealing the cork sea-t 9 in position, which may be readily accomplished by forcing plaster of Paris or other suitable cementing substance in the passages 12 so as to fill them and the said space between the surface 11 and the bottle neck, as clearly shown at 13 in Figs. 1 and 2.

For the purpose of arranging a closure of the bottle against ingress of liquid while in any angular position, I provide a valve which is somewhat in the form of a dumbbell with spherical heads 14, 15, and a rigid connecting link 16. The head 15 and the link 16 are, by preference, composed of glass or porcelain, while the head 14 is of some fioatable material, such as cork. Both the heads 14, 15, are greater in diameter than the opening in the valve seat 3, while the head 15 is considerably larger than the other, for the purpose of acting as a weight to insure the seating of the head 14 on the seat 3 when the bottle is horizontal or in a more upright position. The head 14 is made of floatable material so that the ingress of liquid will automatically tend to seat it on the seat 3 when the bottle is in any inverted angular position.

As shown in Figs. 1 and 2, the walls of the bottle neck adjacent the inside of the shoulder' 2 are cut away so as to form, in effect, a flared portion; and this is in order that the head 15 will roll down hill, so to speak, when the bottle is horizontal or in a more erect position, thus positively forcing the head 14 onto the seat 3.

In operation, when it is desired to draw off the contents, the bottle is tilted in the customary manner, after removing the cork 1 0; when the parts will take the position shown in Fig. 2, thus permitting a tortuous egress of the liquid. If attempt be made'to ll the bottle While it is in a horizontal or more upright position, the Weight of the head 15 Will seat the head 14 on the valve seatV 3. .If the same attempt be made, by the aid of a vacuum, While the bottle is inverted, the eiect of the suction Will be to draw the head 15 tightly onto the seat 3, thereby preventing the creation of a vacuum Within the bottle. In any position, the cage 5 prevents the insertion of a mechanical device for obstructing the operation of the valve, While permitting the free passage of liquid therethrough.

VItis to be understood that various changes may be resorted to in the form, `construction Yand arrangement of the several parts Without departing from the spirit and scope of my invention, and hence I do not intend to limit myself to the speciic details herein shovvn'and described except as they may be set forth in the claim, but

What I claim is i Y A non-'reflllable bottle comprising a double valve seat located in the neck of the bottle, the said valve seat having inwardly flaring sides, a cork seat permanentlyV se-V cured in the mouth of the bottle and anV Copies of this patent may be obtained for five cents each, by addressing the Commissioner of Patents, Washington, D. C.
